Dr. Robin Berzin: Why Perimenopausal Women Start HRT Too Late and When the Research Says to Start

Most women doing everything right in perimenopause still feel exhausted, foggy, and frustrated by belly fat that won't shift. This is not a willpower problem. It is an estrogen problem, and most women are being told to wait when they should be acting now. In this episode, I sit down with Dr. Robin Berzin, founder of Parsley Health, to explore why belly fat accumulates around the middle as estrogen shifts, why 43% of ADHD diagnoses in women hit between 41 and 50, and why estrogen loss drives brain fog and dopamine decline that most doctors are missing. Dr. Berzin also makes the case for starting hormone therapy early and shares what data from 120 million women tells us about HRT, dementia risk, and long-term protection for your brain, bones, and heart.
